Simon Nash updated TUSCANY-1341:
--------------------------------
Attachment: simple-callback-ws.zip
This is patch 6, containing a new sample simple-callback-ws showing callbacks
across Web services. It has no build-time dependencies on patches 1 through 5
but it needs all these other patches to be applied in order for it to run
correctly.
This patch contains the complete code for the sample. It should be unzipped to
the sca/samples directory.

> The callback function using WS bindings doesnt appear to be operation. So

> 1) WebServiceBindingProcessor.java
> - The resolve() method does not setup the callbackInterface on its
> InterfaceContract resulting in NPE.
